Analytical Perspectives State-by-State Obligations for Grant Programs
from the 2018 President's Budget

Visualizing select U.S. Federal Government grant programs on a state-by-state basis, this alluvial diagram (Sankey) shows the flow of obligation data from the federal government to the states. Using the latest D3.js methods, this Sankey also employs a few novel features: utilizes Crossfilter for fast n-dimensional filtering across multiple variables within the data set; transforms tabular data into a graph representation of the data that adheres to the Sankey layout of nodes and links. This transform function is patterned after the work of DensityDesign Lab developers Giorgio Caviglia, Michele Mauri, Giorgio Uboldi, and Matteo Azzi; hides lowest level of graph hierarchy to avoid clutter when all agencies are shown; labels only the top n-percent of nodes on the lowest level of the graph hierarchy to further avoid clutter; and uses the tidyverse R package to wrangle, munge, and tidy the data.
